Cheryl Gillan: The hon. Gentleman has pursued that issue, and I hope that the Minister will have taken note. It is important that the Government consider alternative fuels, particularly in the light of the detrimental effect on our environment of the fuels that are currently in use.
	The report concluded that aqua methanol should be introduced as soon as possible, so the question is why there are not yet any clean aqua methanol vehicles on our city streets. The answer is that the Europe-wide fuel
	tax rules are blocking their introduction. They mean that aqua methanol would cost some £1.90 a litre at the pump and, obviously, that is a commercially impossible price.
	Fortunately, after thorough investigation and confirmation of the report’s findings under the coalition Government, the Treasury has now agreed to make the tax changes necessary to enable the new fuel to be competitively priced against diesel in the UK by putting it on a level playing field with other gas-based fuels. It announced its intention to do so in the two most recent Budgets and autumn statements and finally included the necessary legislation in the last Finance Bill, just before the recent election. However, the change has still not been enacted, because in the wash-up process the Opposition objected to it despite the fact that the entire green fuel challenge project to demonstrate the need for aqua methanol and prove its worth in exchange for the tax change was initiated and completed during their time in government.
	I am now hopeful that the Chancellor will take the measure through on 8 July, so the debate is meant to emphasise the importance to health of enacting this new fuel tax measure immediately. Equally importantly—we have yet to have an undertaking from Government on this—we must integrate the fuel into the DFT’s fuel strategies and funding programmes to accelerate its introduction. The importance of doing that as soon as possible can hardly be overstated.
	It is unlikely that many people will have heard of aqua ethanol until now, but those with long memories will remember the green fuel challenge, which aimed to foster the development of greener transport fuels. Of the three groups selected for support, the highest award was given to Zero-m Ltd, a company in my constituency. Its proposition was that converting commercial diesel vehicles to aqua methanol offered many advantages, including reducing particulate emissions from diesel engines and lower NOx, which is the diesel exhaust gas responsible for forming smog and acid rain, and which is central to the formation of tropospheric ozone.
	Further, the company also discovered that renewable aqua methanol could be made more easily and cost-effectively than most, possibly all, other proposed green transport fuels. In addition, as if that were not enough, it discovered that substituting aqua methanol for diesel would improve UK fuel security and reduce our exposure to politically volatile crude oil prices, because aqua methanol is derived not from crude oil but from the huge and growing global resource of natural gas. Importantly, from the climate change point of view, it can also be made from a wide range of renewable sources, including, rather amazingly, renewable electricity and the carbon dioxide in the air, turning that controversial little climate change bugbear into a jolly good friend.
	By introducing methanol made from plentiful natural gas in the short term—so-called brown aqua methanol—we can immediately strengthen the fight against diesel pollution, and at the same time, relatively quickly, win CO2, fuel security, exports and job benefits. Once brown aqua methanol is established, it can be replaced down the track by chemically identical green renewable methanol once that form becomes economically viable when compared with diesel. Brown natural gas-based methanol paves the way and acts as that solid bridge to
	near-zero-CO2 green methanol, without requiring the massive Government subsidies that would be incurred in trying to go directly to the green form without using the brown bridge.
	Between them, the members of the Zero-m team have the most amazing experience. Together they have more than a century of expertise in alternative fuels, so these constituents of mine really do know what they are talking about. They particularly understand how oil markets work and the importance of minimising the need for Government subsidies, because oil prices can go down as well as up. When they go down—and history shows that they can stay low for a long time—subsidies that looked fairly short-term and affordable can suddenly look very high and indefinite. In fact, they can become, as they often have in the past, completely unsustainable economically.
	With long experience of seeing high-cost alternative fuel projects fail because Governments cancelled the subsidies when oil prices fell, Zero-m’s approach throughout has been to find a way to introduce a fuel that will be commercially viable when oil prices are low. It is interesting to note, anecdotally, that before the second world war it was believed that there was only 12 years’ worth of oil left at the then consumption rate of about 8 million to 10 million barrels a day. Today, the numbers in BP’s June 2015 statistical review show that apparently we have 52 more years of reserves at the 2014 global consumption rate of 92 million barrels a day. Therefore, we are using about 10 times more oil today and it is going to last four times longer than they thought it would last in 1935.
	Although it is probably true that oil could run out at some distant point in the future, the oil industry has a habit of finding new deposits and even cheaper means of extracting ever more from them, extending today’s problem with pollution into the future.
	Zero-m believes that aqua methanol could be the earliest commercially viable alternative, because it only needs launch support to begin replacing diesel made from oil. Of course, it has to be remembered, but rarely is, that the more that subsidised alternative fuels displace oil, the greater the over-supply of oil will become and the lower the oil price is likely to go. That is the Catch-22 of developing alternative fuels: they look good when the oil prices are high, but if they succeed they will almost inevitably cause oil prices to fall.
	Biofuels are one of the key planks of the European Union strategy to reduce emissions, but a 2015 departmental report on options for energy transport policy to 2030 showed that crude oil prices in excess of $250 a barrel are needed before most anticipated renewable biofuels can become commercially viable on a stand-alone basis. Even the Government are expecting bioethanol and biodiesel to need heavy taxpayer subsidy far into the future through the renewable transport fuels obligation.
	It is surely worrying that even that Government report accepts that biofuels are not expected to be commercially viable even by 2030, and possibly far beyond. Add to that the fact that including biodiesel in diesel fuel does virtually nothing to reduce particulates and NOx, the key city street-level pollution issue, and that, even worse, including biodiesel in normal fossil
	diesel actually reduces miles per gallon. It seems to me that aqua methanol is one initiative that can definitely be foreseen to be commercially viable at today’s low oil prices of around $65 a barrel, which is massively below the over $250 a barrel that the Government are expecting biodiesel to cost in 2030, as set out in the report I referred to earlier.
	Zero-m has calculated that, in terms of particulates and NOx reduction, converting one diesel van to aqua methanol, at an estimated cost of £5,000, is equivalent to converting five cars to electricity, which costs the Government at least £25,000 in subsidies. Converting one heavy goods vehicle, at an estimated cost of £15,000, would deliver the same diesel fume reductions as converting 30 cars to electricity, at a cost of more than £150,000. If the Government funded, say, £5,000 for each van and £15,000 for each HGV converted to aqua methanol, that investment could save them £20,000 and £135,000 respectively, versus what it would cost via the electric car route, and still achieve the same result.
	When it comes to cutting street-level diesel pollution, aqua methanol has the ability to give us a significantly bigger bang for our tax pound than relying mainly on the introduction of electric vehicles—or indeed of hydrogen vehicles, which are likely to be even more expensive, with commercial viability even further into the future. However, despite all that promise, aqua methanol is still not an integral part of the Department for Transport’s published alternative fuels strategies and funding plans, even though all common sense suggests that it should be strongly backed to accelerate and bolster current efforts to tackle the awful diesel pollution problem. Waiting for electric cars or hydrogen buses to fix the problem is being tried, and has been tried for some time, but still the diesel pollution worsens, with consequential health problems compounding the costs to the Government.
	Tonight I am asking the Minister to add this potentially powerful new string to the Government’s bow in the urgent battle to improve air quality. The proposed tax change is the culmination of over 14 years of Government-initiated and sponsored work to investigate this exciting new fuel and then enable its introduction. The new tax measure has been approved by all relevant Government Departments, including the Treasury, the relevant legislation has been drafted and all necessary consultations have been completed successfully. There is nothing further that the Treasury needs to do now beyond including the measure in the Finance Bill on 8 July, with an early implementation date.
	I have worked alongside my constituents on this journey, and it has been a long and painful one. We are very grateful that the Treasury has now heard the message. Aqua methanol can and should be a major and effective part of the solution to this problem, and it would require no financial support from the Government after the introductory phase.
	I am sure that the Government will now enact the promised deferred tax change. Tonight I am asking the Department for Transport to complete the picture and integrate aqua methanol fully into its published strategies and funding policies. Without the tax change, the launch of aqua methanol is economically unviable and will not occur, and all the fine opportunities and valuable benefits will be forgone. However, without the other half of the equation—the Department for Transport—supporting
	aqua methanol, both financially and with publicity, our city air will continue to be full of dirty diesel particulates and NOx for much longer than it need be. With both those steps in place, Ford, Mercedes, Iveco, Scania and DAF, to name just a few of the most popular van and HGV manufacturers in the UK, could start making and importing clean aqua methanol-capable vehicles into the UK.
	I would like to applaud the Minister and the Chancellor of the Exchequer for having the foresight to see that aqua methanol deserves to be put on the same taxation footing as other natural gas-based transport fuels. Now I also urge them to redirect funds from some longer-term, higher-cost initiative, such as hydrogen, just as the Department is already doing for compressed and liquid natural gas. Given the severity of the pollution problem, continuing with the status quo is not an acceptable or justifiable option. By being an early adopter, we can improve our environmental credentials. I hope that the Minister will give a response that encourages my constituents and enables us to kick-start the introduction of aqua methanol, so that we can clean up our air as quickly as possible.
